Explanation:
The elements that are present in group 17are fluorine, chlorine, bromine, iodine, and astatine. They are called halogens as they react with metals to give salts. The electronic configuration of the outermost shell of theelements of group 17 is ns2 and np5. Therefore there are 7 electrons in theoutermost shell.
Number of electrons = Group Number -10
=17 - 10
=7
Therefore , they have 7 electrons in their outermost(valence) shell.
